Celtics president of basketball operations Danny Ainge has targeted the regular-season opener as the date to expect Rajon Rondo’s return to action, and the point guard’s agent agrees.“That sounds right,” Bill Duffy said yesterday at the Orlando summer league. “We don’t want to put any pressure on him and overanticipate, but the main thing is to be healthy and 100 percent. He’s on target in his rehab and we anticipate a 100 percent return.”Duffy doesn’t expect Rondo to suffer from the uncertainty that continues to hound Chicago Bulls point guard Derrick Rose’s return from knee surgery.

“I think Rajon’s (knee surgery) was less severe, so he’s more optimistic,” Duffy said. “I don’t think that’s Rajon’s nature. He’s not going to be as patient. But psychologically he’ll be fine. That was a big hurdle for Rose, but Rajon isn’t made that way.”Nor does Rondo appear to be bothered by the latest round of trade rumors.“He’s been going through that for the last three years,” Duffy said. “He’s just used to it.”
